Welding the Inconel 718 Superalloy Reduction of Micro-segregation and Laves Phases explores the day-to-day welding business in Alloy 718 and presents solutions to avoid or minimize micro-segregation. It considers the limitations of changing from lab scale models to actual production models and presents new technologies with proven experimental background.
Alloy 718 nickel-based superalloy is widely used in intense environments due to its excellent mechanical properties and high corrosion resistance at elevated temperature. Its high strength is mainly derived from the metastable and coherent phase γ″ (Ni 3 Nb) with partial contribution from coherent and ordered phase Ni 3 (Al,Ti).
Inconel 718. Inconel 718, often referred to as ‘the workhorse of super-alloys’, is a precipitation hardenable nickel-based alloy designed to provide high yield, tensile, and creep-rupture properties at temperature ranges from cryogenic up to 1400⁰F (760⁰C). Common applications of Inconel 718...
Inconel 718 is a nickel-chromium-molybdenum alloy designed to resist a wide range of severely corrosive environments, pitting and crevice corrosion. This nickel steel alloy also displays exceptionally high yield, tensile, and creep-rupture properties at high temperatures.
